摘　　要：针对大型石油储液罐在地震中的抗震性能,本文建立了大型储液罐的三维有限元模型,并分析了储液灌的动力特性及流固耦合对于大型储液罐抗震性能的影响。结果表明,考虑流固耦合时,储罐会出现明显"象足"失稳现象,所以在对大型储液罐抗震设计时,应加强储液罐底部的抗震能力。In order to analyze the seismic performance of large-size liquid storage tanks, nite element model of liquid storage is established in this paper. The dynamic character liquid-solid coupl phant foot＂ buck more attention in ng on seismic performance ing phenomenon appears by the seismic design. three dimension fi and the influence of of tanks are analyzed. The results show that, obvious ＂ele considering liquid-solid coupling. Therefore it should be paid
